Efimov correlations in strongly interacting Bose gases
Marcus Barth, Johannes Hofmann
We compute the virial coefficients, the contact parameters, and the momentum distribution of a strongly interacting three-dimensional Bose gas by means of a virial expansion up to…
Pairing effects in the non-degenerate limit of the two-dimensional Fermi gas
Marcus Barth, Johannes Hofmann
The spectral function of a spin-balanced two-dimensional Fermi gas with short-range interactions is calculated by means of a quantum cluster expansion. Good qualitative agreement i…
Clock shift in a strongly interacting two-dimensional Fermi gas
Christian Langmack, Marcus Barth, Wilhelm Zwerger +1
We derive universal relations for the radio-frequency (rf) spectroscopy of a two-dimensional Fermi gas consisting of two spin states with a resonant S-wave interaction. The rf tran…
Tan relations in one dimension
Marcus Barth, Wilhelm Zwerger
We derive exact relations that connect the universal -decay of the momentum distribution at large with both thermodynamic properties and correlation functions of two-com…
